' Specification of Letters Patent.

Patented June 11, 1912.

Original application filed February 15, 1905, Serial No. 245,719. Divided and this application 11 September 27, 1910. Serial No. 588,991.

by'me on February 15, 1905, serially 1111mm bered 245,719.

This invention relates to refrigerating apparatus of the kind in which liquid is cooled or frozen by being partially evaporated in a chamber or receptacle in which a vacuum is maintained.

An object of this invention is to provide a refrigerating ap aratus which will operate with an efiiciency itherto unattainable.

Thisand other objects I attain by means of an apparatus embodying the features herein described, and illustrated in the drawings accompanying this application and forming a part thereof.

In'the drawings, grammatically, partially in section and partially in elevation, a refrigerating machine embodying my invention.

The apparatus illustrated consists of a refrigerating chamber, a series of fluid actuated ejectors operating in tandem, and a condenser adapted to receiv the fluid discharged by the ejectors.

The refrigerating chamber illustrated,

consists of a stationary head 1 and a removable mold 2 adapted to receive the liquid to be cooled or frozen. temporarily secured to the stationary head The mold 2 may be by any suitable means which provide for a fluid tight joint between the mold and the head. ,The liquid to be frozen, which will be hereinafter referred to as water, for convenience ofdescription, is preferably introduced into the mold 2 in the form of spray from a suitable and controllable source of supply, through an inlet pipe 3, which projects through. the stationary head .1. pipe 3 preferably terminates in a pipe ring or rose lprovided with a series of holes from which the water falls drop by drop or in a thin stream.

The refrigerating chamber communicates with the inlet 5 of a fluid ejector 6 by means of suitable pipin 7 which communicates ,with a port, provi ed in the head portion 1.

I have illustrated dia-.

The

The outlet or discharge port 8 of the eject 6 communicates, through piping 9, with the inlet 10 of a fluidejector 11. Both the fluid .ejectors 6 and 11 are preferably operated by steam which may be delivered through a common delivery pipe 12, communicating with a suitable sourceof fluid or steam supply. i

The outlet or discharge port 13 of the 4 ejector 11 communicates by means of. a pipe or piping 14 with the inlet 15 of a suitable condenser, for example, a jet condenser 16 the condensing liquid of which, for example water, is derived from a suitable source of supply through a pi e 17 The operation of the apparatus is as ollows:

When a vacuum, or a partial vacuum, is

created inthe refrigerating chamber or in the head portion 1 and the mold 2, by the combined action of the ejectors 6 and 11, the water, slowly introduced through the ring 4, is partially evaporated, thereby causing a fall in temperature in the refrigerating chamber which cools or freezes the remainder of the water falling into the mold 2. The vapor given off by the water is meanwhile exhausted by lthe ejector 6 and the. operating fluid of this ejector together with the vapor withdrawn from the refrigerating chamber is exhausted by the ejector 11. All of the fluid delivered to the series of ejectors employed and all of the va or withdrawn from the refrigerating-cham er by the ejectors is discharged into the condenser 16, and

is then condensed. When the condensing water is plentiful and the temperature is low, so that a bi h degree of vacuum can be obtained in t e .condenser 16 the series of fluid actuated ejectors, may be operated by an elastic fluid, such as steam, at atmospheric pressure. The

condenser 16 may be provided with auxiliary means for maintaining a vacuum, ifthe degree of vacuum obtained is not suflicient.

What I claim is: 1 A freezing machine, comprising a refrigerating chamber, a series of fluid actuated ejectors communicating therewith and operating in tandem, and a condenser communicating with the last ejector of the series. I

2. -A freezing machine, comprising. refrigerating chamber, a primary fluid ejector communicating with said chamber and adapted to exhaust fluid therefrom secondary fluid ejector receiving the fluid discharged from said primary ejector, and a Condenser communicating with the exhaust of the secondary ejector.

3. A freezing machine comprising a rev fluid discharged from said primary ejector,

and a condenser communicating with the exhaust of the secondary ejector and receiving the fluid discharged therefrom. 1

4. A freezing machine comprising a re,-

frigerating chamber, a primary fluid ejector communicating therewith, a secondary fluid e ector IBCBlVlIlg the fllllCl dlscharged from said prnnary e ector, a condenser communr eating with the exhaust of the secondary ejector and receiving the fluid discharged therefrom, and means for admitting a record of the case in the Patent Oflice.

5. A freezing machine comprising a refri crating chamber, means for introducing a f ow of water to be cooled or frozen into said chamber, a steam actuated ejector communicatingwith said chamber and adapted to create a vacuum therein, a second steam actuated ejector communicating with the exhaust of the first ejector and receiving the steam and vapor exhausted therefrom, and a a jet condenser communicating with the exhaust of said second e ector and receiving all the fluid discharged therefrom.' 1
